BMW Genuine Fuel Injector for N54/N63

The BMW Genuine OEM fuel injector, part number 13538616079, represents the latest "Index 12" revision for N54 and N63 engines. These Piezo high-pressure fuel injectors are crucial for optimal engine performance and precise tuning. A malfunctioning injector can lead to significant issues such as rough idling, misfires, and overall poor engine operation. BMW has iterated on this design multiple times, and this latest version incorporates all factory updates and revisions, ensuring superior reliability and performance compared to older designs or aftermarket alternatives. Manufactured in Italy, this genuine BMW injector features a protective cap on its tip. This cap serves a dual purpose: it shields the injector tip from contamination and maintains compression on the Viton seal. When installing new injectors, a mandatory calibration process is required. The unique adjustment value, found on the injector itself, must be recorded before installation and used during the calibration procedure to ensure accurate fuel delivery. This injector is compatible with a wide range of BMW models, including various iterations of the 135i, 1M Coupe, 335i, 335xi, 335is, 535i, 535xi, X5, X6, and Z4, primarily from the 2007-2016 model years, with specific engine fitments for N54 and N63 (N63A) engines. It's important to note that injectors with index 10 or lower have different calibrations and construction than those with index 11 or higher, and cannot be mixed within the same cylinder bank. For modified vehicles or optimal performance, replacing all fuel injectors simultaneously is highly recommended. When installing, it is also advised to replace the decoupling element (part number 13537564751).
